Application filed October l5, 1902. Serial No. 127,360. (No model.)

To all whom it may concern,.-

Be it known that'I, EDWARD MoMrEssoN MORGAN, doctor of medicine, aresident of the town of Westmount, in the district of Montreal, Provinceof Quebec, Dominion of Can* ada, have invented certain new and usefulImprovements in Beaters for Eggs, Cream, 85e.; and I do hereby declarethat the following' is a full, clear, and exact description of the same.

My invention may be. said, briefly, to consist in lproviding a beater orwhipper for eggs, cream, or the like having a pair of dashers revolublein opposite directions and adapted to pass through one another duringtheir revolution; and it further consists in the speoilic constructionand arrangement of the parts thereof.

For full comprehension, however, of my invention reference must be hadto the accompanying drawings, forming a part of this speciiication, inwhich similar reference characters indicate the same parts, and wherein-Figure l is a side elevation of a beater or whipper constructedaccording to my invention, and Fig. 2 is a similar view taken at rightang'les to Fig. 1.

Each dasher consists of a single length of wire, bent to form an eye cat its upper end, and a resilient loop c, extending from said eye toabout midway the length of the beater,While the dasher end proper, f, isbent into substantiall y liattened volutoid form, the convolutions ofone dasher being of diderent measurement to the correspondingconvolutions of the other to allow the dasher ends proper to passthrough one another. These dashers are carried and actuated by a pair ofpinions g, one located at each side of and intermeshing with adrivinggear 7L, pivoted upon a frame This frame consists of a piece of Xform having' a pair of cross-pieces ,7' at each end thereof and offsetslightly to positions beyond the driving-gear- The pinions g arerotatably mounted upon pins upon the inner sides of the cross-pieces,and each pinion has a radial arm f; and the arm 7o upon the upper pinionbeing longer than the arm upon the lower pinion and having the eyes atthe ends of the dasl1erarms pivoted thereon, While the arm Zhas acranked arm m rigidly upon the end thereof and projecting across itscarrying-pinion, the end of this cranked arm having a headed stud nthereon. The resilient loops of the beaterarms are sprung over the outerend of the arm l and the stud a, respectively, and the loop of thebeater-arm sprung over the arm Zis of greater length than the loop ofthe other arm.

The supporting end of the carrying-frame consists of a piece of wireo,bent in the forln of a U, with the ends of its legs sprung bctweenprojections p upon the main carryingframc and bent inwardly toward themiddle thereof, where said ends are inserted in holes in the frame,where they are held by the riveted end o of the stub-spindle of the maingear, while the supporting end proper, fr, is olfset at right angles andpresents a curved bearingsurface, and a correspondingly curved wire s issecured at its ends, as at t, to the bends in said bearing end, thusconstituting a substantially circular or oval support. The arm Z uponthe lower pinion is disposed a less distance from the center of itscarrying-pinion than the stud n, the object being to give one beater athrow that will describe an oval,while the other beater will describesubstantially a circle, this being caused by the diiferent throwscombined with the same extent of lift and depression imparted by theupper pinion.

An advantage of having' one beater of greater area than the other isthat a iiow of the substance being beaten will constantly follow thebeater of larger area even if such beaters revolve in oppositedirections.

What I claim is as follows:

l. In a beater the combination with a carrying-frame, of a pair ofdashers having a reciprocating' and oscillating movement, and means forreciprocating said dashers in opposite directions in a vertical plane.

Q. In a beater the combination with a carrying-frame, of a pair ofdashers having a reciprocating and oscillatingl movement, means forrotating said beaters in opposite directions in a vertical plane, andmeans for causing' said beaters to follow paths of different contour andlongitudinally of the beater, for the purpose set forth.

3. In a beater the combination with a car- IOO rying-frame, of a maindriving-gear rotatably mounted upon said carrying-frame, a pair ofpinions one located above and one below said main driving-gear, a pairof dashers, means connecting said dashers to said pinions and meanscoacting with said pinions whereby said dashers have'imparted thereto areciproeating and oscillating movement.

4. In a beater the combination with a carrying-frame, of a maindriving-gear rotatably mounted upon said carrying-frame, a pair ofpinions one located above and one below said main driving-gear, acrank-arm upon said lower pinion, a pair of dashers pivotally connectedat their upper ends to the upper pinion and slidably connected to eachend of said crank-arm, said dashers having a reciprocating andoscillating' movement substantially as described and for the purpose setforth.

5. In a beater the combination with a carrying-frame and a pair ofdashers having a reciprocating and oscillating movement, of a rotarypart having apair of pivot-points thereon at different distances fromthe center, means for rotating` said rotary part, means forreciprocating said dashers with their upper ends coinciding, and meansfor slidably connecting said dashers to said pivot-points upon therotary part.

6. In a beater the combination with a carrying-frame and a pair ofdashers having a reciprocating and oscillating movement, of a pinionhaving a pair of pivot-points thereon at different distances from thecenter, means for rotating said pinion, means for reciprocating saiddashers with their upper ends coinciding, and means for slidablyconnecting said dashers to said pivotpoints upon the pinion.

7 In a beater the combination with beating or whipping means of asupport adapted to rest upon the receptacle containing the substancebeing beaten or whipped and consisting of a single length of rigid wirebent to present a pair of rigid legs supporting the beating or whippingmeans at their upper ends and having a complete annular horizontalbearing part at their lower ends of a diameter greater than that of thehorizontal orbit of the whipping means, substantially as described andfor the purpose set forth.

8. In a beater the combination with a carrying-frame of X form havingcross-pieces at its upper and lower ends and offset therefrom, adriving-gear rotatably mounted upon one side of said frame between saidcross-pieces, a pair of pinions rotatably mounted upon the sides of thecross-pieces opposite to that upon which the main driving-gear ismounted and intermeshing with said main driving-gear, a radial arm uponthe upper pinion, a radial arm upon the lower pinion and having acranked arm thereon of greater length than the radial arm, a pair ofdashers pivoted at their upper ends to the arm upon the upper pinion andslidably connected midway of their length to the arm upon the lowerpinion and the end of the cranked arm thereon, respectively said dashershaving a reciprocating and oscillating movement and a support for saidframe, substantially as described and for the purpose set forth.

9. A flat dasher-arm made from a single piece of wire bent at its lowerend into substantially volutoid form in the longitudinal plane of thedasher-arm and means for reciprocating such dasher-arm and moving thevolute bodily in a direction at substantially right angles to its flatside, substantially as described.

10. A dasher-arm made from a single piece of wire bent to form an eye atits upper end, a resilient loop extending from said eye to about midwaythe length of said dasher and its lower end bent into substantiallyvolutoid form in a plane longitudinally of said dasherarm, substantiallyas described.

11. In a beater, a pair of dashers each comprising a strand of volutoidform the volute of one being of less area than that of the other andmeans for `V`reciprocating such dashers in opposite directions with eachvolute passing bodily through the other in a direction substantially atright angles to its Hat side and causing a flow constantly in the samedirection.

12. In a beater the combination with means for reciprocating a pair ofdasher-arms, of a pair of dasher-arms reeiproeatcd by said means inopposite directions with a reciprocating and oscillating movement thedasher ends proper of said arms being of substantially volutoid form andeach in a plane longitudinally of the arm of which it forms a part, andthe eonvolutions of one being of dierent measurement to thecorresponding convolutions of the other, substantially as described andfor the purpose set forth.

13. A dasher-arm consisting of a strand bent to present substantially atriangle with its base at one extremity thereof and Ameans forreciprocating such dasher-arm and moving the triangular portion thereofbodily in a direction at substantially right angles to its flat side.

14. In a beater, a pair of dashers each comprising a strand of volutoidform bent to present substantially a triangle with its base at oneextremity, the volute of one being of less area than that of the otherand means for reciprocating such dashers in opposite directions with onevolute passing through the other and causing a flow constantly in the same direction.

In testimony whereof I have aixed my signature in presence of twowitnesses.
